HORSESHOE.

SPECIFICATION forming part of Letters lPatent No. 435,104, dated August28, 1890.

` Application filed March 3, 1888. Sera1No.266,055. (No model.)

.To all whom it may concern:

Be it known that I, WILLIAM SOMERVILLE, Sr., of the city of Buffalo, inthe county of Erie and State of New York, have invented a new and usefulImprovement in Horseshoes, of which the following is a specification.

This invention relates to that class of horseshoes which consist of anupper plate, which is secured to the foot of the hors'e, and a lowerplate or shoe, which is detachably secured to the upper plate andprovided with sharp calks, as shown, for instance, in Letters Patent ofthe United States N o. 322,652, granted to me July 2l, 1885. In thehorseshoe described in the said Letters Patent the rear ends of thecalk-plate are provided with tenons, which enter between lugs formed onthe rear ends of the upper plate. This construction, while answering thepurpose, requires considerable labor for fitting the parts together.

The object of my present invention is to provide a simpler means forsecuring the rear ends of the calk-plate to the upper plate; and itconsists of the improvements which will be hereinafter fully set forth,and pointed out in the claim.

In the accompanying drawings, Figure l is a perspective view of theshoe, showing the two plates thereof separated. elevation of the shoe.Fig. 3 is a vertical longitudinal section thereof. Fig. t is acrosssection in line Fig. 3. Fig. 5 is a horizontal section in line y y,Fig. 3.

Like letters of reference refer to like parts in the several figures.

A represents the upper plate, having the form of an ordinary horseshoeand provided with the usual nail-holes, so that itcan be secureddirectly tothe foot of the horse.

B represents a toe-lug formed on the under side of the front end of theplate A, and C C represent heellugs formed on the under side of the rearends of said plate. The upper plate A is provided at its front end inrcar of the toe-lug B with an opening b.

d d represent downwardly projecting tongues or tenons formed on theunder side of the upper plate A, a short distance in front of theheel-lugs C C.

E represents the lower plate, which is made of the proper form to fitagainst the under Fig. 2 is a side side of the upper plate A, and isprovided at its front end with a sharp toe-calk F, and near its rearends with sharp heel-calks G G. The lower plate E is provided at itsfront end above the toe-calk F with a forwardly-projecting tenon h,which enters the opening b in the upper plate A, and secures the frontend of the lower plate to the upper plate.

t' t' represent openings or sockets formed in the lower plate E, nearthe rear ends thereof, and receiving the tenons CZ of the upper plate.The tenons d hold the rear ends of the lower plate E against lateralmovement on the upper plate A. The straight rear ends of the lower platebear against the straight front sides of the heel-lugs C of the upperplate. The rear ends of the lower plate E, in which the sockets t' areformed, are preferably enlarged, as shown, to give the shoe the properstrength at these points.

j represents transverse seinicireular grooves or depressions formed inthe straight front faces of the heel-lugs C C, and 7c are similargrooves formed in the adjacent straight faces of the rear ends of thelower plate E, which grooves form with the grooves j circular openings,in which are inserted locking pins or bolts Z, as clearly shown in Figs.2 and 3. These locking-pins firmly secure the rear ends of the lowerplate E to the upper plate of the shoe. The grooves j 7c are formed bydrilling a hole through the contiguous portions of the heellugs O C andthe rear ends of the lower plate E after the plates have been placedagainst each other. The locking-pins Z, when inserted in the grooves j7o, tend to force the lower plate forwardly on the upper plate, the pinsbeing preferably made slightly larger in diameter than the grooves, andthe sockets z' in the lower platelarge enough to permit a slight forwardmovement of the tenons CZ in the sockets. Any looseness between the twoplates by reason of shrinkage of metal, or in fitting the plates, orfrom other causes, can be mthus readily taken up by the pins Z andaperfectly firm and rigid fastening of the lower. calli-plate to theupper plate obtained. This construction forms a cheap and reliablefastening, which requires butvery little fitting,

and enables the shoe to be constructed very light and at small cost.When the calks of the lower plate become worn, the latter can be IOOreadily detached from the upper plate to sharpen its calks by removingthe lockingpins Z, or be replaced by a new calk-plate when its calksbecome Worn to such an extent as to render the plate unserviceable.

I claim as my invention- In a horseshoe, the combination, with an upperplate A, provided with a toe-lug B, an opening b, arranged in rear ofsaid toe-lug, heel-lugs C C, having straight front faces, transversesemicircular grooves j, vformed in said front faces, anddownwardly-projecting tenons d, arranged in front of said heel-lugs, ofa lower calli-plate E, provided at its front end with an upwardly andforwardly projecting tongue h, which engages in the opening b, andhaving straight rear ends fitting again st the front faces of theheel-lugs C C, transverse selnicircular grooves la, formed in the rearends of the calli-plate E, opposite the grooves j, and forming with thegrooves j a circular opening intersecting the'adjacent meeting ends ofthe two plates, sockets t', adapted to receive the tenons d, andcylindrical locking-pins l, arranged in the circular openings formed bythe grooves j and 7c, whereby the rear ends of the calli-plates areattached to the upper plate, substantially as set forth.

Witness my hand this 25th day of Feb- 3o ruary, 1888.
